It is for this reason that the artist is in a sense, a neuroscientist, exploring the potentials and capacities of the brain, though with different tools. How such creations can arouse aesthetic experiences can only be fully understood in neural terms. Such an understanding is now well within our reach. The first step is to understand better the common organization of our visual and emotional brains, before we can even proceed to enquire into the determinants of neural variability. But there is little reason to doubt that a study of variability, of how a common visual activation can arouse disparate emotional states, will constitute the next giant step in experimental studies of the visual brain.
In such a study neuroscientists would do well to exploit what artists, who have explored the potentials and capacities of the visual brain with their own methods, have to tell us in their works. Because all art obeys the laws of the visual brain, it is not uncommon for art to reveal these laws to us, often surprising us with the visually unexpected. Paul Klee was right when he said, "Art does not represent the visual world, it makes things visible." We hope that the enormous international enthusiasm that a study of the neural basis of aesthetic experience has generated will prove an effective catalyst in encouraging the neural study of other human activities that may seem remote from the general discipline of neurobiology. It is only by understanding the neural laws that dictate human activity in all spheres - in law, morality, religion and even economics and politics, no less than in art - that we can ever hope to achieve a more proper understanding of the nature of man.
